Multiplayer Join Server Issue

I created a main menu on the third person shooter blueprint with a host game, quit, and server list. One client hosts the game, then the second client sees it in the list. For the list, each item in the list is a button. When the button is clicked it does nothing. There is an OnClick event tied to the button, and everything seems correct based on several tutorials. Am I missing something? Blueprints are attached in images.
